Contour-informed inter-patient deformable registration of Head-and-Neck patients
Xingyue Ruan, Xia Li, Muheng Li +4
Background and Purpose: Voxel-based analysis (VBA) helps to identify dose-sensitive regions by aligning individual dose distributions within a common coordinate system (CCS). Accur…
Gaussian Primitives for Deformable Image Registration
Jihe Li, Xiang Liu, Fabian Zhang +4
Deformable Image Registration (DIR) is essential for aligning medical images that exhibit anatomical variations, facilitating applications such as disease tracking and radiotherapy…
TAMBRIDGE: Bridging Frame-Centered Tracking and 3D Gaussian Splatting for Enhanced SLAM
Peifeng Jiang, Hong Liu, Xia Li +3
The limited robustness of 3D Gaussian Splatting (3DGS) to motion blur and camera noise, along with its poor real-time performance, restricts its application in robotic SLAM tasks.…
CPT-Interp: Continuous sPatial and Temporal Motion Modeling for 4D Medical Image Interpolation
Xia Li, Runzhao Yang, Xiangtai Li +3
Motion information from 4D medical imaging offers critical insights into dynamic changes in patient anatomy for clinical assessments and radiotherapy planning and, thereby, enhance…
Continuous sPatial-Temporal Deformable Image Registration (CPT-DIR) for motion modelling in radiotherapy: beyond classic voxel-based methods
Xia Li, Runzhao Yang, Muheng Li +4
Deformable image registration (DIR) is a crucial tool in radiotherapy for analyzing anatomical changes and motion patterns. Current DIR implementations rely on discrete volumetric…
